Thanks for help...

Hi Christian,
     otool -L gives following output

otool -L  /Users/vikrant/Applications/ghc/lib/ghc-6.8.2/ghc-6.8.2
/Users/vikrant/Applications/ghc/lib/ghc-6.8.2/ghc-6.8.2:
        /opt/local/lib/libreadline.5.2.dylib (compatibility version 5.0.0, current version 5.2.0)
        /opt/local/lib/libncurses.5.dylib (compatibility version 5.0.0, current version 5.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.0.0)
        /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)


out those libraries, I do not have following libraries on my system. I fighting to get those installed through macports. my guess is it should work as soon as I install those.

 /opt/local/lib/libreadline.5.2.dylib (compatibility version 5.0.0, current version 5.2.0)
 /opt/local/lib/libncurses.5.dylib (compatibility version 5.0.0, current version 5.0.0)

Are you sure? My binary should try to link against the GNUreadline framework. Which program did you try to link?

What does "otool -L" say to your file /Users/vikrant/Applications/ghc/lib/ghc-6.8.2/ghc-6.8.2

My output is as below
